Did you drop the Y pipe to do this? I made two extension cables and now that it’s stopped raining here I plan to swap the connections instead of the sensors to ensure the problem moves with the sensor first, then will replace the bad one. If I end up dropping the pipe I'll replace both for sure. Welding in a new bung has some appeal, sure would make the job simpler next time.
actually access to the passenger downstream O2 wasn’t crazy bad. Just the material was so degraded I was p*sing into the wind expecting to replace a new sensor in the old hole. I’m pig headed and didn’t give up soon enough.
I drove the car about 5 times with nothing in the hole at all. I’d rather not have but didn’t have a choice. Didn’t have any adverse effect it seems.
With the new bung and sensor, cleared the codes, CEL still off after 50 miles.
just the grief I had for 2 days, trying to make the old hole work, when I could have just snipped the wire, and welded on the plug.
and the Bosch sensor was less than $40. Just snip/weld, see if that fixes it - is a whole lot better than swapping cables, sensors etc.
